        set srcaddr "all"
        set internet-service enable
        set internet-service-id 65646
        set action accept
        set schedule "always"
        set utm-status enable
        set av-profile "g-default"
        set ssl-ssh-profile "certificate-inspection"
        set nat enable
    next
end

Result

In addition to the IP addresses, IP address ranges, and services allowed by Google.Gmail, this policy also allows the traffic which accesses 10.1.100.0/24 and UDP/53 and 172.16.200.0/24 and TCP/80-443. At the same time, the traffic that accesses 2.20.183.160 is dropped because this IP address and port is disabled from Google.Gmail.
